The company shared the news in a blog post Tuesday, writing the new collaboration with Taco Bell will delight consumers “with a unique ride-thru experience.”

Lyft riders will be able to select the in-app Taco Mode option to make a pit stop for “the ultimate Taco Bell experience,” including a free Doritos Locos Taco for the first ride, a special menu and more.

Taco Mode will be launched as a pilot program between 9 p.m. and 2 a.m. during two date periods: July 27-29 and Aug. 3-5 in Orange County, California. Lyft has plans to expand the late-night deal to additional markets before the end of 2017, and eventually roll the program out nationwide in 2018.
